How do the JoWo omniflex and JoWo (leonardo) elastic nib compare in terms of flex, feed keeping up, smoothness and overall performance?

Here's a brief comparison of 3 modern flex nibs: Conklin Omniflex, Noodler's Ahab, Fountain Pen Revolution Flex. Ease of flex Conklin Omniflex FPR flex Noodler's Line variation FPR flex - the nib writes finer "naturally" Noodler's Conklin Omniflex Railroading They all railroad at some point but it depends so much on how quick, how often and how hard you flex that this is really where I need to call in the YMMV. That being said, my Ahab is the most reliable and sturdy. Nib "feel" Conklin Omniflex feels the most fragile: the metal seems the thinnest, and I don't dare pushing it too much, Noodler's Ahab feels the sturdiest of the three, smooth even flexed to its maximum. Normal writing FPR has the finest line and feels almost italicized, a bit dry and doesn't keep up well with my rather fast writing. That might be something I can fix with brass sheets etc but I don't want to alter the line variation so I'll wait! Noodler's pleases me the most: smooth, a fine medium, still wet, always keeps up. Conklin: meh, nothing to say. Conclusion As much as it kills me to say it, the FPR flex nib is the best in terms of flex, you can get very "calligraphic" with it. The Conklin Omniflex just feels too fragile to me - I must be able to feel comfortable otherwise I might as well go back to dip pen nibs. The Ahab is just the most versatile of all: I love it as an everyday writer, I still love flexing it even after the beautiful discovery of FPR nib. I'll try to swap the FPR nib onto the Ahab and see how I like it (as I don't like the Himalaya V2 pen that much) but I'm pretty sure I want to keep the Ahab as is.

I've been wanting to get into flex pens ever since I started using fountain pens a few years ago, but didn't want to get ahead of myself. So I started off with all the recommended beginner pens. I've been writing with all my pens for awhile and now I'm itching to get into flex but would like some recommendations. I've been watching a bunch of youtube videos and curious which flex pen most people here think has the best performance. I hear vintage flex is where its at, however I can't afford vintage flex so I have to stick to modern flex for now. Here are the modern flex pens I am aware of. Pilot FalconPilot Custom 912 - FA NibFPR Himalaya V2 Ultra FlexNoodlers Ahab, Boston, Creaper, Konrad, Neponset, tripleConklin OmniflexEdit - Desiderata PensLike I mentioned above I'm curious what the community thinks is the best performing modern flex pen and feel free to let me know of other ones that is worth looking into. I know mileage will vary.

Duraflex by Conklin I bought it from Singapore for months already, the pen is wonderful in looking, big size, all black with rose gold details, affordable, and limited edition with individual number engraved on the barrel... Oh wow, you name it, it has it. I finally use the pen days ago, using Iroshuzuku Murasaki-Shikibu (a wonderful purple colour). I have the pen flushed before using, and yes, within 20 minutes, I regret it. Very disappointed. As mentioned on many forums around, hard start problem appears as frequent as it can and it rails even not pressing hard for some line variations. I could withstand the rail problem as I can use it as a normal pen and not pressing it. But the hard start thing.....uuuuug. T_T The pen needs to break in? or that's the way of the omniflex nib? or other kind of ink may help? Guys, anything I can do? Please share your opinions. Thanks

I ordered this pen with much anticipation, but during the wait, noticed a few negative experiences with the omniflex nib expressed online. I must admit I was dreading what my experience would be when the pen turned up and hoped I hadn't wasted my money. Anyhow, the pen arrived and I fell in love with it the first moment I saw it. The Cracked Ice finish is so very attractive. The packaging was gorgeous too, I'm not a packaging kind of person, and would normally much rather a quality product as I throw the packaging away but in this case I will definitely keep the box. I feel like I've really treated myself to something special. My Falcon was more expensive granted but the looks, feel and presentation paled in comparison. Onto the writing experience. To avoid any hard starts etc and then some overflexing by myself as a result, my shiny nib was pulled straight out of it's housing and doused in boiling water to clean off any residue. I lined it up with the feed and put it back into the pen and loaded it up with Noodler's Apache Sunset. I thought if I'm going to test out a flex pen I may as well use a shading ink. I picked this pen up at 7am and have been writing non stop with it for 3 1/2 hours and am glad to say, I'm so impressed with it. The other flexi nibs I own are on the Ahab, Nib Creaper and Pilot Falcon and this has definitely gone to the top of the list. It has to be the easiest to flex by a fair bit and I find it returns to it's thinner state quicker than the Noodlers Pens, meaning the line width within one stroke is so much more variable. I was mindful to not overflex it, so didn't push it further than I thought it could go, and that made for some serious variation anyway so I'm really pleased with the nib as it is. No hard starts, no rail roading. The feed kept up with everything I threw at it. I can't compare it to any vintage nibs, as I haven't tried any as yet, but as a modern alternative and albeit relatively affordable, surely this has got to be a good way of doing it. I'm really impressed with Conklin, and the pen itself. My next purchase will be the same pen in another colour with a different nib. For balance in this review, the only negative I have is that where my fingers hold the grip, I unfortunately seem to untighten the section and barrel while writing. This may not be the case for everyone, and could very well be unique to my hand shape and pen hold. If I have any issues later on down the line I will update this thread.
